just a FYI, all the part numbers in this thread is good for the M939 trucks as well..

rear axle

I'm bringing this up because I plan on replacing the rear bearings and seals on my M817. I've read the TM, this thread several times and several others.

I see that the bearings are lubricated with grease and the axle oil is prevented from getting to the bearing by the inner seal. Also I've seen talk of alternative seals than OEM...but have a hard time understanding the part number references, if they are the OEM (old style or new).

Has there been updates to these seals? I've already got Timken 596, 593 and cup 592a coming and want the seals that last, while OEM seem to have wear problems. Please help to clarify which seals to get?

HELLO JAKELC15, i discovered your post referring to a speedi-sleeve 99212 for repairing grooved axles, and wanted to know if this in fact would fit an m939a2 rear axle shaft wear the ctis seals ride, my axles suffered wear grooves from my CTIS seals and are now leaking because of this. hoping for some good news thanx

I'll look up the speedi sleeve for this

 

[Jakelc15]

This sleeve should fit the shaft 4.750" Might check that measurement since you have it apart.

99363 http://www.skf.com/us/products/seal...ndex.html?designation=99363&unit=imperialUnit
One is 1/2" wide and the other is a little over 3/4. I'm not sure which would fit best. Both have the removable flange.

Uncle suggests changing the ctis and hub seals every 6000 miles but we never do!

Love dead thread revivals, but just for clarity, it is the outer seal that keeps the axle oil out of the hub cavity. M939a2 does not have outer seal on rear hubs, outer bearing is oil lube. Inner is grease.

Yep...

Murphy's law...bought the bearings and seals then sold the truck.

The real problem turned out to be the transfer case.

I have a full rear set, bearings and seals, in classified.
